Abstract (en)
[origin: WO2014204440A1] At least some of the disclosed systems and methods employ one or more seismic receivers that gather seismic data from a plurality of positions in a borehole that penetrates a formation. Further, at least some of the disclosed systems and methods employ a memory to store the gathered seismic data. Further, at least some of the disclosed systems and methods employ logic that inverts the seismic data for simultaneous determination of asymmetric axis velocity (V0) and Thomsen parameters, epsilon (ε) and delta (δ), in a tilted transversely isotropic (TTI) model.
